​The main idol of the Million Stars, (The “Haruka” of Million Live) Mirai is a bit dumb to the point where when asked, “Which era was Oda Nobunaga active in?” she responded with, “the past!” In the Gessan Manga she joined many clubs because she didn’t know what to do until Shizuka invited her to watch a performance at the 765Pro Live Theater. After watching Shizuka perform she was inspired to become an idol.​

She became interested in seiyuus after watching Fullmetal Alchemist with her mother. Haruka is a huge Makoto fan and MikiP, when Akky was a guest on MilliRadio she went on about why she liked Miki. She hates water because it is tasteless. Has a radio show with Aimi that started last year. She is also a huge Disney fan and talks about it on her radio show often. Has a cat named Michelle.
